To all whom it may concern: I Y

Be it known that 1', SAMUEL E. SHAFER, a citizen of the United States,residing in the county of Elkhart and State of Indiana, have inventedcertain new and useful improvements in Molds, of which the following isa specification.

My invention relates to cement molds and has particular reference to acement post mold.

in object of the invention is to provide a mold adapted to formcylindrical or tapered posts having extensions thereon adapted to serveas braces.

A further object of the invention is to provide a post having theseextensions so disposed as to be adapted for use in either corners orstraight line fences.

in important object is to provide means braces may be varied withoutaltering the construction of the main portion of the device.

Another object is to provide a device of, this character which isinexpensive in its manufacture, simple and efficient in opera tion, anddurable in service.

Other objects will be made apparent during the course of the followingspecification.

Referring to the drawings wherein is;

Referring more particularly to the. drawings, the numerals 1 and 2designate upper and lower mold sections which are preferlocks adapted tocooperate.

2 eyes.

ably formed tapered. These upper and lower sections fit together and areprevented from displacement by means of a band 3, which is secured tothe upper section 1 and overlaps the lower section 2, as shown at 1. Thesections 1 and 2 are composed of semicylindrical plates, 5 and 6, and 7and 8, re-

spectively. In order to secure the semi-cylindrical plates together uponthe inner face of the plates 6 and 8 I provide longitudinal strips 9secured as by rivets adjacent their rear edges upon said plates 6 and 8.The plates 6 and 8 have their edges spaced slightly away from saidplates. This construction provides pockets 10 for the reception of theedges of the plates 5 and 7. In order to prevent accidental displacementof the tvo semi-cylindrical portions, 1 provide a plurality of staples11 adjacent the edges of the plates 5 and 7 adapted to be engaged by acorresponding number of eyes 12 secured upon the adjacent edges of theplates 6 and 8. After the eyes 12 have been placed over the staples 11looking pins 13 are inserted to prevent the displacement of the v Itwill be noted that the band 3 is formed in two parts having their edgesin alinement with the edges of the two main semi-cylindrical plates. Bythis construction it will be seen that after the two lowersemi-cylindrical plates 7 and 8 are placed together and locked by meansof the staples, eyes and pins 11, 12 and 13, and the upper plates 5 and6 are assembled in the same manner and locked over the lower section 2by means of the band 3, a rigid frusto-conical shell is provided.

In order to form wings or extensions to serve as braces for the post, Iprovide brace molds indicated as a whole by the numeral 1 1. These bracemolds comprise triangular plates 15 having their lower edges 16 rolled.The rear edges of too plates 15 are bent as shown at 1'7, and areadapted for slidable engagement with similarly bent strips or guides 18secured upon the plate 8. The

plates 15 are arranged in pairs and are spaced apart and are inalinement with openings 19 formed in the plate 8. It will thus be seenthat the space between the plates 15 is in effect a continuation of thespace within the fi'usto-conical mold. In order to hold the plates 15 intheir spaced relation 1 provide locking tubes 20 adapted to fit withinopenings 21 in the plates. These locking tubes are tapered and aresubstantially oil'- cular in cross-section. The tubes 20 are split andone edge is bent inwardly upon the tube as shown at 22 and then bentagain as shown at 23 to form a pocket 24. These locking tubes areinserted within the openings 21 in the plates 15 and are expanded toengage the same firmly by means for sliding locks These sliding locksare formed of a strip of metal having one edge adapted to engage thepocket 24 and having its other edge bent to form a pocket 26 adaptedtoengage the free edge 2'? of the tube 20. An extension 28 is providedupon the sliding locks, said extension being provided with an opening 29to form a grip for withdrawing the sliding lock from the locking tubes20.

In order to close the brace mold 14 I provide closure plates 30 having aflange 31 formed upon one edge and adapted to engage the rolled upperedge 32 of one of the plates 15. The other edge of the plate 30 isprovided with a flange 33 adapted to embrace the outer face of the otherplate 15. One end of the plate 30 is formed curved for engagement withthe cylindrical section 2. One side of the plate 30 is locked on theplate 15 by the aforesaid flange 31 and the other side is secured bymeans of a hasp 34 which is adapted to engage a staple 35 secured uponthe other plate 15 and prevented from displacement by means of a lockingpin 36.

vVhen it is desired to form a post for use in corners of a fence it isdesirable to use two of the corner braces 14. It will be noted thatthese corner braces are disposed at right angles to each other, althoughI do not limit myself in this particular, and thus provide adequatebracing against the strain of the angular fencing. When it is desired toform a post for use along straight line fences it will be found that onebrace is sufficient. In order to adapt the mold for forming a post ofthis description, I provide a plate 37 which fits within the bent strips18 and closes the opening in the plate 8. This plate 37 is provided witha handle 38 to facilitate its removal or insertion.

In order to strengthen the lower portion of the section 2, I provide acurved bar 39 which encircles the lower part of the section 22 passingthrough the lower locking tubes 20. The ends of the bar 39 are adaptedto pass through openings 4O in angular members 41 secured upon plate 8and are provided with openings 42 for the reception of locking pins 43.

After the mold is set up as shown in Fig. 1, the brace molds 14 may befilled with cement and the plates 30 secured in place thereon and thesections 1 and 2 filled with cement or the plates 30 may be secured inplace upon the molds 14 and cement poured into the sections 1 and 2 in asuffioiently liquid state to flow into the molds 14 through the openingsin the plate 8. In either event the plates 30 prevent the cement fromcoming out of the molds 14. The plates 5 and 7 are provided withopenings 44 forthe insertion of staples or other wire securing means.After the mold has been removed from the molded structure, and thelocking tubes 20 have been removed, the resultant holes extendingthrough the braces are of service when fencing is secured to the post.In said forms of wire stretches an anchor chain is used. These holes inthe braces are particularly adapted to receive such a chain.

It will be understood that various changes in the shape, construction,and arrangement of parts maybe resorted to without departing from thespirit of the invention or limit ing the scope of the subjoined claims.

Having thus described my invention What I claim is 1. A post moldcomprising a cylindrical shell provided with a plurality of openingsextending upwardly from its lower edge, and brace molds connected withsaid shell in alinement with said openings, said brace molds comprisingspaced parallel side plates, a detachable closure plate, and means forlocking said plates in their spaced relation.

2. A post mold comprising a cylindrical shell provided with openingsextending upward from its bottom edge, guides secured upon said shelladjacent said openings, and brace molds detachably connected with saidshell, each of said brace molds comprising triangular side platesextending upward to the top of said openings, flanges on the edges ofsaid plates slidable within said guides, a detachable top closure plate,and collapsible means for holding said side plates in their spacedrelation, either of said openings being adapted to be closed by anarcuate plate slidable in said guides.

3. In a device of the comprising a cylindrical shell provided with anumber of openings in the lower part, a brace mold comprising flangedtriangular plates adapted to slidably engage guides secured upon thelower portion of said shell, a plate for closing the upper portion ofsaid brace mold and means for locking said triangular plates in theirspaced relation, said locking means comprising split tapered tubeshaving one edge bent inwardly to form a pocket and expanding meanscomprising a tapered strip, having one edge adapted to engage withinsaid pocket and the other edge bent to form a pocket for engagement withthe free edge of said locking tube. I

4. In a mold, an-upright portion having openings therein extendingupwardly from its lower edge, retaining strips secured to said uprightportion on each side of the character described,
